Data APIs

If you are building a decentralized applications, chances are that you will need to query on-chain data. Since building a full indexer is not always feasible, the community has created a set of APIs that you can use to query data from the NEAR blockchain.

These APIs provide a simple way to access on-chain data without having to run your own indexer or node. They are designed to be easy to use and provide a wide range of functionality, from querying account balances to exploring transactions and blocks.

FastNEAR API​

FastNEAR allows to easily query the NEAR blockchain to get an account's assets, map keys into account IDs, explore a block's transactions, etc.

Possible use cases include:

  • Querying all assets of an account (including fungible and non-fungible tokens)
  • Querying the last block produced
  • Mapping Public Key to Account ID
  • Mapping Full Access Public Key to Account ID
  • Knowing a user's staking pools (validators)
  • Querying the top holders of a token

NearBlocks API​

NearBlocks provides an endpoint to query actions that happened on a NEAR account, possible use cases include:

  • Query an account balance
  • Query all function calls to specific contract
  • Get total NEAR supply and circulating supply
  • Query the number of total transactions on NEAR

Pikespeak API​

Pikespeak allows you to fetch blockchain events and aggregated analytics on wallets, validators, delegators, money transfers, dApps activity, and more.

Use case includes:

  • Querying account balances
  • Querying the most active wallets
  • Querying historic account events
